[wxPython] wxOGLConstraints, anyone ever use them?

I've been messing around with the OGL library, and I'm finding that either I
don't understand the constraints or there's a problem with the library.
Instantiating a constraint always gives me a memory access error (at around
0x00010, so possibly a null pointer error). Without the constraints I just
wind up with the sub-elements of the composite shape at 0,0.

What I'm doing is one of those classic "wiring diagramme" apps where you
give people black box components and they script them by dragging
outputs/attributes to inputs/attributes. To do that I'm planning on having
a composite shape something like this:

[ title here in box ]
[input] [output]
[input] [output]
[input] [output]
[input]
       [attr(I/O)]
       [attr(I/O)]
       [attr(I/O)]
       [attr(I/O)]

Right now I'm considering just switching to OpenGL (at which I'm far more
proficient than wxOGL) for the UI, but I'd like to know if other people have
actually worked with this part of wxPython so I'll know for future projects
whether to go down the road again.

Enjoy yourselves,
Mike(y)
